Charge Transfer Inefficiency:

• Summary: We have developed a model of the readout process of the STIS CCD which is able to reproduce the effects of CTI seen in STIS CCD imaging and spectroscopic data. Using this model we have implemented a pre-processor for CALSTIS which removes these CTI effects prior to further processing.
